Shoe Re-Treader

I have some good shoes. I buy them on a regular basis. The body of them is very sturdy, but the soles get worn out too fast. I designed these as a solution to this, but I haven't been able to build them because I don't have the right materials, specifically I need some plate steel for the bottom and sides of the press. Anyway, if you would like to build these and show the results I would love to see that.
